PIVOTED DISCHARGE-ARM.

Application filed May 1, 1918.

To all whom it may concern:

Be it known that we, BERT R. BENJAMIN and CLINTON A. Hnoxnoxn, citizens of the United States, and residents, respectively, of Oak Park, in the county of Cook and State of Illinois, and of Western Springs, in the county of Cook and States of Illinois, have invented certain new and useful Improvements in Pivoted Discharge-Arms, of which the following is a full, clear, and exact specification.

Our invention relates to binding mechanism, and more particularly to bundle discharging mechanism for binders utilized in binding corn, grain, and other crops.

The object of the invention is to increase the effectiveness and efficiency of the bundle discharging mechanism, and to render certain parts thereof more compact while permitting them to perform their discharging function without interfering with other op erative parts of the machine.

With this object in View, the invention comprises a rotatably mounted pivoted -dis charge arm, and means for lifting the discharge arm about its pivot during its rotation in discharging the bundle.

I have illustrated one embodiment of our invention in the accompanying drawings, and in these drawings- Figure 1 shows a side elevation of the m vention Fig. 2 is a top plan View, partly in section, and taken at right angles to Fig. 1; and

Fig. 8 is a detail View showing the pivotal connection of the discharge arm with the sleeve carried by the binder shaft.

The invention is utilized in connection with bindin mechanism, such as illustrated in Patent No. 649,731, Johnston, May 15, 1900, in which the binder shaft is disposed vertically, and the pivoting of the discharge arm is necessitated by reason of its location with respect to the main harvester wheel.

The binder shaft 10, illustrated in the drawings, is provided with a sleeve 11 secured thereto, and this sleeve is provided with an outwardly extending bracket 12 having upwardly extending bearing members 13. These bearing members, as clearly illustrated in Fig. 3, are located at an angle to the longitudinal axes of the binder shaft for reasons which will be hereinafter ex- Specification of Letters Patent.

Serial No. 231,901.

plained. A discharge arm 14 ispivoted in the bearing members 13 on an axis disposed at an acute angle with the longitudinal axis of the binder shaft. A cotter pin 15 is carried by the bearing members 13 in a plane above the pivotal connection of the discharge arm 14, and this cotter pin limits the upward movement of the. discharge arm. The outer end of the discharge arm, as shown at '16, is bent at an angleto the remaining portion, and is disposed in a substantially horizontal plane. A bracket 17 is rigdly secured to the frame 18 of the harvester, and carries an upwardly and out: wardly extending cam l9,which contacts with the discharge arm in the rotation of the latter, and lifts the arm in such a manner that it avoids contacting with the harvester wheel. will now be explained.

In order to fulfil its discharging function the discharge arm 14 is rotated in a clockwise direction (see Fig. 2), and in its rotation forces the bundle -away from the binding mechanism and discharges it from the harvester. In this discharging operation the bundle exerts a counterpressure against the discharge arm, and by pivoting the discharge arm on an inclined axis applicants utilize this counterpressure in forcing the discharge arm downwardly against the lower wall of the bracket 12. In devices hereinbefore employed, it has been found that this pressure of the bundle against the discharge arm tends to raise the discharge arm on its pivot, thereby preventing the arm from fulfilling its function, but by means of the inclined pivot this difficulty is avoided, and the discharge arm is maintained in operative position until the bundle is discharged. After discharging the Patented Jan. 6, 1920.

The operation of the device bundle the arm comes in contact with the cam 19, and is raised for a portion of a revolution until after the arm is passed beyond the path of the harvester wheel.

From the above description it will be seen that we have provided a novel construction, well adapted to fulfil the func-' the invention as set forth in the following claims.

What We claim as new is:

1. In a harvester, a substantially vertically disposed binder shaft, discharging mechanism pivotally carried thereby, and means for lifting said discharging mechainism on its pivot during a portion of its revolution, said discharging mechanism be ing pivoted to said shaft in such a manner that the pressure of the grain thereagainst tends to force said mechanism downwardly.

2. In a harvester, a substantially vertically disposed binder shaft, a discharge arm 4. In a harvester, a substantially verti-- cally disposed binder shaft, a discharge arm carried thereby and mounted on a pivot inclined downwardly and forwardly, and

means for limiting the downward movement of said discharge arm about its pivot.

5. In a harvester, a substantially vertically disposed binder shaft, a discharge arm carried thereby and mounted on a pivot inclined to the horizontah'm'eans for limiting the movement of said discharge arm about its pivot, and means for lifting said discharge arm during a portion of its revolution.

6. In a harvester, a substantially vertically disposed binder shaft, a discharge arm carried thereby and mounted on a pivot inclined downwardly and forwardly when said discharge arm is in bundle engaging position, means for limiting the upward and downward movement of said discharge arm about its pivot, and means for lifting said discharge arm during a portion of its revolution about the binder shaft.

In testimony whereof we affix our signatures, in the presence of two witnesses.
